The time from infection to illness is about two days.
Yearly influenza epidemics can 3 affect all age groups, but the highest risk of complications occur among children younger than age two, adults age 65 or older, and people of 4 age with certain medical conditions, such as chronic heart, lung, kidney, liver, blood or metabolic diseases, or weakened immune systems.

Drugs for influenza are 10 in some countries and effectively prevent and treat the illness. Some influenza viruses develop 11 to the antiviral medicines, limiting the effectiveness of treatment.
Influenza epidemics occur 12 during autumn and winter in temperate regions. Illnesses result in hospitalizations and deaths mainly among high-risk groups. Worldwide, these annual epidemics result in about three to five million 13 of severe illness, and about 250 000 to 500 000 deaths.
Influenza can cause serious public health and economic problems. In 14 countries, epidemics can result in high levels of worker absenteeism and productivity 15 . 16 most people recover from a bout(轮) of influenza, there are large numbers of people who need hospital treatment and many 17 die from the disease every year. 18 is known about the effects of influenza epidemics in developing countries.
The most 19 way to prevent the disease or severe outcomes from the illness is vaccination. Vaccination is especially important for people at higher risk of serious influenza complications, and for people who live with or care 20 high risk individuals.

Across the world, 1.1 billion people have no access to clean drinking water. More than 2.5 billion people lack basic sanitation. (卫生设备)
The combination proves deadly. Each year, diseases related to inadequate water and sanitation kill between 2 and 5 million people and cause an estimated 80 percent of all sicknesses in the developing world. Safe drinking water is a precondition for health and the fight against child death rate, inequality between men and women, and poverty.
Consider these facts:
●The average distance that women in Africa and Asia walk to collect water is 6 kilometers.
●Only 58 percent of children in sub-Saharan Africa are drinking safe water., and only 37 percent of children in South Asia have access to even a basic toilet.
●Each year in India alone, 73 million working days are lost to water-borne diseases.
Here are three ways you can help:
Write Congress
Current U.S. foreign aid for drinking water and sanitation budgets only one dollar per year per American citizen. Few members of Congress have ever received a letter from voters about clean drinking water abroad.
Sponsor a project with a faith-based organization
Many U.S. religious groups already sponsor water and sanitation projects, working with partner organizations abroad. Simply put a single project by a U.S. organization can make safe water a reality for thousands of people.
Support nonprofit water organizations
Numerous U.S.-based nonprofits work skillfully abroad in community-led projects related to drinking water and sanitation. Like the sample of non-profits noted as follows: some organizations are large, other small-scale, some operate worldwide, others are devoted to certain areas in Africa, Asia, or Latin America. Support them generously.
72. The three facts presented in the passage are used to illustrate that________.
A. poverty can result in water-borne diseases
B. people have no access to clean drinking water
C. women’s rights are denied in some developing countries
D. safe drinking water should be a primary concern

74. The main purpose of the passage is to call on people to _________.
A. get rid of water-related diseases in developing countries
B. donate money to people short of water through religious groups

A device that stops drivers form falling asleep at the wheel is about to undergo testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called Driver Alert, aims to reduce deadly road accidents by 20% - 40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to fatigue.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots, gives out a sound about every four minutes during a car journey. After each sound the driver must respond by squeezing the steering wheel (方向盘). A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
According to the text, Driver Alert ______.
A. aims to reduce tiredness-related accidents
B. has gone through testing at laboratories
C. aims to prevent drivers form sleeping
D. has been on sale for 12 months
73. How should a driver respond to the sounds from Driver Alert?
A. By sounding a warning. B. By touching the wristband.
C. By checking the driving time. D. By pressing the steering wheel.
74. We can learn form the text that the driver needs to stop for a break when his response time is ______.
A. about 400 milliseconds B. below 500 milliseconds
C. over 500 milliseconds D. about 4 minutes
75. When the driver gets sleepy while driving, Driver Alert ______.
A. moves more regularly B. stops working properly
C. opens the window for the driver D. sounds more frequently and loudly
Parents often believe that they have a good relationship with their teenagers （青少年）. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut.” Joanna noted.
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up （蜷伏）with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what’s on their minds. “In fact, parents are first on the list.” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should crate chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.
56．“The door to his room is always shut” suggests that the son .
A．is always busy with his studies B．doesn’t want to be disturbed

A．their daughter isn’t as lovely as before
B．they can’t read their daughter’s mind exactly

A．Teenagers talk a lot with their friends.
B．Teenagers do not want to understand their parents.
C．Teenagers do not talk much with their parents.
D．Teenagers talk little about their own lives.

A．Parents are unhappy with their growing children.
B．Parents have suitable ways to talk with their teenagers.
